随着水电厂综合自动化水平的提高,其计算机监控系统已成为覆盖全厂信号、控制操作的综合性信息系统,通过计算机监控系统直接将远程终端装置(RTU)控制系统数据上送到调度中心,实现遥测、遥信信息资源共享和高速数据交换,直接在远程主站显示、控制。可取消传统RTU,避免重复投资,是将来RTU改造的一个方向。
With the improvement of integrated automation of hydropower plants, the computer monitoring system has become a comprehensive information system covering the entire plant signal and control operation. The data of the remote terminal unit (RTU) control system is directly sent to the dispatch center through the computer monitoring system, To achieve telemetry, remote information sharing and high-speed data exchange, direct display, control at the remote site. Can cancel the traditional RTU, to avoid duplication of investment, is a direction of future RTU transformation.
